Unfortunately this meant an audience of one--the one who sat between the earpieces of the stethoscope. With modern obstetrics came the other disciplines of science as applied to medicine, and one of these benefits was ultrasound. Whether you actually see the baby on a screen or hear the baby's heartbeat on a little speaker, the technology is similar: Physical structures are sensed by reflection of sounds emitted toward them and by changes in motion, and electrical signals are reproduced based on these reflections. Depending on the device used, these electrical "signatures" are translated into either audible sounds or visible images. The visible images are readily seen, but audible signals may take a little longer into the pregnancy to pick up because, unless you can see what you're aiming for with ultrasound pictures, trying to aim for the fetal heart can be a daunting challenge when the baby and heart are small. But typically... With modern Doppler devices, a fetal heartbeat can be heard from 10-12 weeks, although not hearing them up to 12 weeks is not particularly worrisome. With only a stethoscope you'd have to wait until about 18-20 weeks. A common mistake is to hear the radiated blasts of the maternal heart rate in this area. This can be easily distinguished from the fetal heart rate by merely taking the mother's pulse. If the mother's pulse is different (and slower!) from what you're hearing on the Doppler, it's the fetal heart you're hearing. Also, the fetal heart rate is much faster in early pregnancy than in later pregnancy. In the first trimester, the fetal heart rate (FHR) is usually above 140/minute, and sometimes as high as 180.

The heartbeat is best hear when the child's spine is close to the uterine wall. You should be able to press firmly and hear a fetal heart beat at 19wks, with the bell side of your stethoscope.
